TES

TES [ISRO]

TES (Technology Experiment Satellite), weighing 1108 kg, is an experimental satellite to demonstrate and validate, in orbit, technologies that could be used in the future satellites of ISRO. Some of the technologies that are planned to be demonstrated in TES are attitude and orbit control system, high torque reaction wheels, new reaction control system with optimised thrusters and a single propellant tank, light weight spacecraft structure, solid state recorder, X-band phased array antenna, improved satellite positioning system, miniaturised TTC and power system and, two-mirror-on-axis camera optics. TES will also carry a panchromatic camera for remotesensing experiments.

TES might be the prototype of an indian military reconnaissance satellite.
